APPARATUS FOR SPECIFICATION forming part of Letters Patent No. 772,387, dated October 18, 1904.

Application filed August 20, 1902.

To all whom it may concern:

Be it known that we, JOHN TITUs, a resident of Oyster Bay, and WILLIAM TITUs, a resident of Old W'estbury, in the town of North Hempstead, in the county of Nassau and State of New York, citizens of the United States, have jointly invented certain new and useful Improvements in Apparatus for Tempering Air; and we do hereby declare that the following is a'full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, which is a vertical sectional view of an apparatus comprising our said invention.

This invention is designed for the economi cal production of air tempered by the removal of undue moisture and by heating to any required degree for respiratory uses, as required in hospitals, dwellings, mariufactories, and the like in the amelioration of unhygienic or unsanity conditions or for curative or other purposes.

A is a chest intended to contain ice, a mixture of ice and salt, or any other suitable refrigerating material.

Bis an air-conducting pipe, preferably of boiled construction, which extends through the refrigerating-chest and which is refrigerated by the action thereon of the refrigerating material. Connected with the exit end of the air-conducting pipe is a heating apparatus which may be of any suitable construction, but which, as shown in the drawing, comprises a heatingchamber C, through which are passed tubes or flues a from the fire-box Z) of a suitable furnace, the grate of which latter is indicated at c and the ash-pit at d. The upper ends of the tubes (0 communicate with a conduit 0, common to all. The gaseous prodpreferably, at or near its bottom, as shown at a, with the outlet end of the air-conducting refrigerating-pipe B and also, preferably near Serial No. 120,294. (No model.)

its top, has an outlet for the tempered air, as indicated at g in the drawing. A blower D, operated from any suitable source of power, is provided at the inlet end of the air-conducting pipe B to propel a volume of air continuously through the said pipe B and into and through the heating-chamber C. In the pipe B, adjacent to the blower, is a valve it. The said pipe B, at or near its junction with the heating-chamber C, has a branch pipe E, in which is a valve In the pipe B, between its branch pipe E and its junction with the heating-chamber, is a valve k. From the pipe B at a point between its valve 7t and the outlet of the blower extends a pipe F, the opposite end of which communicates with the heating-chamber. In this pipe F, preferably as near as may be to the blower, is a valve m. At the bottom of each coil of the pipe B is a hanging cup a, which has an outlet-cock 0. These cups collect water condensed from the air as it passes through the pipe.

In the operation of the apparatus (the valves m and being closed and the valves it and Z1 being open) external air is drawn into the blower and by the latter is forced through the refrigerating-coil B, where all superfluous moisture is condensed by the cold and passes off to the cups )2, from which the Water by condensation may be drawn ofi through cocks r. The air thus dried by the elimination of its moisture and purified by like elimination of condensible products, or those which have been held in suspension by-the moisture, passes into the heating-chamber C, where it is either restored to normal temperature for purposes of ordinary respiration or heated to any other preferred temperature proper for the purposes to which the purified and tempered air is to be put. The air makes its exit, of course, from the outlet 9 of the heating-chamber, in which latter may be provided a'valve a to control such exit of the air andmay when desired be conducted to any distance in any direction by any suitable pipe or tube attached at the outlet g.

When for any reason air simply purified and refrigerated is desired, the cock is is closed and the cock 1 is opened, whereupon the refrigerated air passes to the branch pipe E and through and from the latter without entering the heating-chamber. When simply heated air is required, the valves 7b 7c 01' the valves k 2' are closed and the valve m is opened, whereupon the air is shut off from the refrigerator and passes through the pipe F direct to the heating-chamber, from which it may be withdrawn through the outlet 9. By the means described one and the same apparatus with a single blower may be used for the production of an: simply heated, the production of air simply refrigerated with the moisture condensed therefrom,or purified by condensation and removal of moisture therefrom and subsequently raised in temperature to any desired degree.

What we claim as our invention is 1. The combination with a chest for holding refrigerating material, and an air-conducting pipe within said chest constructed and arranged for the removal of water of condensation therefrom, of a heating apparatus connected with the exit end of the said pipe, a valve in said pipe whereby its communication with the heating apparatus may be shut off, a separate pipe extended from the heating apparatus to the air-pipe at a point in the latter remote from its refrigerated parts, and a valve in said separate pipe whereby communlcation may be opened from the blower direct to the heating apparatus, while passage through the refrigerated air-pipe is closed, as

described.

2. The combination with a chest for holding refrigerating material, an air-conducting pipe within said chest constructed and arranged for the removal of water of condensation therefrom, a heating apparatus communicating with the exit end of said pipe, a valve in said pipe, a branch to said pipe having a valve for closing and opening the same, a blower for forcing a volume of air, separate pipe extended to the heating apparatus from or near the outlet of the blower and having a valve for opening and closing passage therethrough whereby air from a single blower may be refrigerated with condensation of moisture therefrom, or heated without such refrigeration or refrigerated with deposition of moisture therefrom and subsequently raised in temperature, as described.
